Ask any questions you have. Don’t worry about any “mistakes” you think you have made. Anything can be fixed. Offer to run trash at the end of your shift -if it ends before it’s dark out. Don’t take anyone or anything too seriously. This is a job, it’s not life and death. The company needs you just as much as they need anyone. Try to have fun. Your coworkers could become your best friends, just be yourself!
